Also, organise the widgets as per your preference by clicking Organize widgets icon. The following capacity charts are displayed in each widgets: Capacity overview: The capacity overview donut chart provides a high-level view of the total storage capacity and how it is distributed between used and available space. You can use this chart to quickly assess overall capacity utilization and determine how much storage remains available. Total capacity Displays the total capacity of the selected storage system. Shown prominently in the center of the chart for quick reference. Used capacity Indicates the amount of storage space that is currently in use. Helps you understand current storage consumption and utilization levels. Available capacity Indicates the amount of storage space that is available for allocation. Helps you determine how much additional data can be stored before capacity is exhausted. Capacity by file system: The capacity by file system chart shows information about the fullest and largest file systems on the storage system. Fullest file systems A chart that shows up to six file systems with the least amount of available capacity. Largest file systems A chart that shows up to six file systems with the largest storage capacity. Each file system is represented by a bar on the charts. To view the following information about the file system, move the mouse pointer over the bar: Capacity The total amount of capacity on the file system, which includes the used and available capacity. Available capacity The total amount of unused storage capacity on the file system. Used capacity The total amount of used storage capacity on the file system. Inodes by independent fileset: Use the following charts to view inode information about the independent filesets that are associated with the storage system. An independent fileset has its own inode space. Other filesets might share the inode space and use inodes from the inode space. These charts are shown only for IBM Storage Scale System storage systems. Fewest available inodes A chart that shows up to six filesets with the fewest number of available inodes. Most inodes A chart that shows up to six filesets with the largest number of inodes. Each fileset is represented by a bar on the charts. Move the mouse pointer over a bar to view the following information for the fileset: Maximum inodes The total number of inodes in the inode space. This value consists of the available inodes and the used inodes. Available inodes The number of inodes that are available in the inode space. Used inodes The number of inodes that are already used in the inode space. This value consists of inodes that are used by this fileset and all dependent filesets. A dependent fileset shares the inode space of an independent fileset. The number of inodes that are used by this fileset are represented by the blue section of the bar. The inodes that are used by dependent filesets are represented by the dark gray section of the bar.
Capacity	Select the storage resources like storage systems, filesets, file systems, or pools from the Components tile. The capacity chart with the default metrics is visible towards the right side. You can also select multiple resources to compare their capacity charts one below the another. Also, type the resource component on the search icon to locate the resource faster. You can add more capacity metrics to the charts by clicking the Add metrics and selecting them. You can customize the capacity charts as per your preference. Select your preferred time zone like browser time zone, system time zone, etc. Set the duration for which capacity information to be investigated Choose the data resolution like sample, hourly, or daily to investigate the capacity behavior. You can export the capacity metrics data in PDF, HTML, and in CSV formats for your reference.

Capacity and usage charts

See the following charts in the classic UI that show the capacity and trends in capacity usage for the file storage systems and their internal resources monitored through data collector:

Total File System Capacity
Capacity by File System
Capacity by Pool and Capacity by File System Pool
Inodes by File System
Inodes by Independent Fileset

Total File System Capacity

The Total File System Capacity chart shows information about available and used capacity for the file systems on the storage system.

Tip: For an IBM Storage Scale System storage system, the available and used capacity information applies to file storage and object storage, if both file and object storage are monitored. For example, the available capacity value is the capacity that is available for use by either the file storage system or the object storage system.

The following information is shown:

Available Capacity: The total amount of available capacity on all of the file systems on the storage system or filer.
Used Capacity: The total amount of used capacity on all of the file systems on the storage system or filer.

Capacity by File System

The Capacity by File System chart shows information about the fullest and largest file systems on the storage system.

The following charts are shown:

Fullest File Systems: A chart that shows up to six file systems with the least amount of available capacity.
Largest File Systems: A chart that shows up to six file systems with the largest storage capacity.

Each file system is represented by a bar on the charts. To view the following information about the file system, move the mouse pointer over the bar:

Capacity: The total amount of capacity on the file system, which includes the used and available capacity.
Available Capacity: The total amount of unused storage capacity on the file system.
Used Capacity: The total amount of used storage capacity on the file system.

Capacity by Pool and Capacity by File System Pool

The Capacity by Pool chart and the Capacity by File System Pool chart show capacity information about the pools in storage systems that are configured for file storage such as IBM Storage Scale System and Storwize V7000 Unified.

Tip: For Storwize V7000 Unified, the chart label Capacity by File System Pool is shown. For IBM Storage Scale System, the chart label Capacity by Pool is shown.

Largest Pools: A chart that shows up to six pools with the largest storage capacity in the storage system.
Fullest Pools: A chart that shows up to six pools with the least amount of available capacity in the storage system.

Each pool is represented by a bar on the charts. To uniquely identify the pool, the pool name is prefixed with the file system name. To view the following information about the pool, move the mouse pointer over a bar:

Capacity: The total amount of file system capacity on all of the Network Shared Disks (NSDs) in the pool, which includes both the total amount of used and free capacity.
Available Capacity: The capacity on all of the free NSDs in the pool. The amount that is shown is the capacity that is available for provisioning new NAS shares.
Used Capacity: The capacity that is being used for file storage on all of the NSDs in the pool.

Inodes by File System

The Inodes by File System charts show inode information for file systems on storage systems that are configured for file storage such as IBM Storage Scale System and Storwize V7000 Unified.

Fewest Available Inodes: A chart that shows up to six file systems with the fewest number of available inodes.
Most Inodes: A chart that shows up to six files systems that have the largest number of inodes.

Each file system is represented by a bar on the charts. Move the mouse pointer over a bar to view the following information for the file system:

Maximum Inodes: The total number of inodes on the file system. This value consists of the available inodes and the used inodes for the file system.
Available Inodes: The number of inodes that are available within the file system.
Used Inodes: The number of inodes that are already used on the file system. Each time that you create a file or directory on the file system, an inode is allocated to the file or directory.

Inodes by Independent Fileset

Use the following charts to view inode information about the independent filesets that are associated with the storage system. An independent fileset has its own inode space. Other filesets might share the inode space and use inodes from the inode space. These charts are shown only for IBM Storage Scale System storage systems.

Fewest Available Inodes: A chart that shows up to six filesets with the fewest number of available inodes.
Most Inodes: A chart that shows up to six filesets with the largest number of inodes.

Each fileset is represented by a bar on the charts. Move the mouse pointer over a bar to view the following information for the fileset:

Maximum Inodes: The total number of inodes in the inode space. This value consists of the available inodes and the used inodes.
Available Inodes: The number of inodes that are available in the inode space.
Used Inodes: The number of inodes that are already used in the inode space. This value consists of inodes that are used by this fileset and all dependent filesets. A dependent fileset shares the inode space of an independent fileset.
The number of inodes that are used by this fileset are represented by the blue section of the bar. The inodes that are used by dependent filesets are represented by the dark gray section of the bar.
